Resetting a Unit on a Stack
Use the following reset command to reload any of the member units or the standby in a stack. If you try to
reset the stack master, the following error message is displayed:
% Error: Reset of master unit is not allowed.
To reset a unit on a stack, use the following command:
• Reset any designated stack member, except the management unit.
EXEC Privilege mode

• Hard reset any stack unit including master unit.
EXEC Privilege mode

Removing an Aggregator from a Stack
To remove an Aggregator from a stack, follow the below steps:
1 Disconnect the stacking cables from the unit. The unit can be powered on or off and can be online or
offline.
2 Log on to the CLI and enter Global Configuration mode.

3 Configure the Aggregator to operate in standalone mode.
CONFIGURATION
stack-unit 0 iom-mode standalone
4 Log on to the CLI and reboot each switch, one after another, in as short a time as possible.
EXEC PRIVILEGE
reload
The switch functions in standalone mode but retains the running and startup configuration that was last
synchronized by the master switch while it operated as a stack unit.
Merging Two Operational Stacks
The recommended procedure for merging two operational stacks is as follows:
1 Always power off all units in one stack before connecting to another stack.
2 Add the units as a group by unplugging one stacking cable in the operational stack and physically
connecting all unpowered units.
